  • Patent number: 9775398
    Abstract: A device fits over a shoe to prevent contaminants from the shoe from soiling a support surface such as the carpet or floor of a home. The shoe has a toe and a heel. The device includes a front section which is shaped and dimensioned to receive the toe of the shoe, and a rear section which is shaped and dimensioned to receive the heel of the shoe. A center section is used to removably connect the front section to the rear section. The center section is fabricated from a resilient material so that it can be expanded to receive the shoe, and then will resiliently contract to grip the shoe.

  • Patent number: 6244352
    Abstract: A shoeing system for horses' hooves comprises a shoe (3) and shoe insert (2) of shock-absorbing material between the hoof and shoe. The single-part or multiple-part insert (2) is matched to the shape of the horse shoe (3) and is nailed in the front area between the hoof and shoe and can move in the rear area with the hoof relative to the shoe. This mobility is ensured by a sliding member (26) situated between the insert (2) and the shoe (3) and capable of moving relative to the shoe. In the heel area, the insert is provided on its inner side with beading (22) which both permits and restricts displacement of the insert.

  • Patent number: 5320184
    Abstract: A shock-absorbing, cushioned horseshoe that substantially absorbs the shock encountered by a horse's hooves and legs when the horse is running or jumping. The cushioned horseshoe is defined by a mounting plate which is adapted with a plurality of interlocking channel members, wherein one of the channel members includes a plurality of longitudinal locking rib members, whereby a nail may be driven through the horseshoe to engage each locking rib member so as to prevent the nail from being inadvertently loosened after the nail has been driven into the hoof of a horse. Fixedly attached to the mounting plate is a ground-engaging sole member that includes openings which are aligned with the holes which are formed in the mounting plate. The sole member consists of a non-slip, wear resistant, resilient material that is adapted for direct engagement with the ground surface.

  • Patent number: 5105891
    Abstract: The invention defines a non-slip, shock-absorbing, cushioned horseshoe that substantially absorbs the shock encountered by a horse's hooves and legs when the horse is running or jumping. The cushioned horseshoe is defined by a base or mounting plate which is adapted with a plurality of boss members having locking holes, and a ground-engaging sole or body member that includes openings which are aligned with the locking holes of the mounting plate so as to receive and lock nails that are driven therein. The sole member consists of a wear-resistant, resilient material that is fixedly secured to the mounting plate for direct engagement with the ground surface. The resilient material is molded to the lower surface of the mounting plate and is received in a V-shaped channel having securing holes disposed therein, whereby the resilient material becomes fixedly secured to the lower mounting surface of the mounting plate during the molding process to prevent separation therefrom.

  • Patent number: 5076366
    Abstract: A heel sock for a horseshoe and formed of a tubular body of yieldable material, such as rubber, neoprene or plastic, such as polyurethane. The body is open at one end and has means at the opposite end for limiting the extend to which the body can be placed on the heel end of a horseshoe. The inner surface of the body will frictionally engage the outer surface of the heel of the horseshoe. A nail can be driven into and through the shoe and into the hoof of the horse. The body can have a projection thereon and integral therewith. In one version, the projection is between the ends of the body and in another version, the projection is near the closed end of the body. The projections give added traction required for muddy or grassy surfaces. In another version of the sock body, the normally lower wall of the body can be wedge-shaped to elevate the heel of the horse in case the hoof surface has been worn or rasped down too much.

  • Patent number: 4844172
    Abstract: A novel shock-absorbing and protective horseshoe comprises a composite shoe that conforms to the shape of the perimeter of the horse's hoof, and from which protrude podded cleats strategically aligned and positioned below the horn of the hoof for providing the prerequisite support for the horse. Each podded cleat has an internal air chamber, which when combined with the complying shape of the external wall partially or fully collapses or deflates the transition of material during collapse, provides a most significant degree of cushioning, thus allowing a relatively high durometer elastomer for the composition of the cleats that would not otherwise provide sufficient compressibility, but has physical properties that surmount the factors of abrasion and wear. Such hard materials are identifiable as having a low frictional resistance in comparison to highly compressible, soft elastomers.
